WATER-COOLING CONTINUOUS CASTING METHOD OF COPPER-IRON ALLOY WIRE ROD

摘要

PROBLEM TO BE SOLVED: To continuously and efficiently cast a high quality copper-iron alloy wire rod having high copper content and to improve the castability, reliability and quality by squeezing up molten copper-iron alloy having high copper content through a nozzle, having desirably round cross section and naturally dropping into cooling water. ;SOLUTION: A molten copper-iron alloy 5 having high copper content is squeezed up through the nozzle 3 under a fixed molten metal pressure and naturally dropped Y into the cooling water 8 and the squeezed molten alloy is cooled with the natural drop Y into the water and shrunk to the squeeze- diameter to cast the copper-iron alloy wire rod 10. Then, the squeezing hole 3a of the nozzle 3 is formed into a round cross sectional shape and the molten alloy 5 is squeezed up into the round cross sectional shape through the squeezing hole 3a. Further, the cast copper-iron alloy wire rod 10 is formed into a coil like copper-iron alloy wire rod 10a in the bottom part of the cooling water 8.;COPYRIGHT: (C)1998,JPO
